11.2.20 HC-003-67: Modbus RTU, inputs (In-A, In-B)
The Modbus RTU module are for use on a RS-485 industrial network. The Module is Compatible with Modbus
implementation guide V1.02 and supports communication speeds up to 115200 bit/s.
Modbus module enables reading of meters by building- and industrial-automation systems.
11.2.21 HC-003-81: BACnet IP, inputs (In-A, In-B)
The Module supports BACnet communication via Ethernet.
The BACnet IP enables reading of meters by building- and industrial-automation systems.
11.2.22 HC-003-82: Modbus/KMP TCP/IP, inputs (In-A, In-B)
The module supports two communication protocols via Ethernet, Modbus TCP and KMP.
The Modbus TCP module enables the reading of the meter via building and industry automation and KMP enables
the reading of current and logged values as well as configurations.
11.2.23 HC-003-83: READy Ethernet, inputs (In-A, In-B)
READy Ethernet module is a plug-and-play module. Once the meter is commissioned, the module starts sending
hourly data on the ethernet network.
Actual values are sent to the utility every hour 24/7/365.
